Please direct questions about Quantum products to Quantum. I have no dates to offer here.

That said, very little changed at the protocol level between Xsan 3 and Xsan 4. The only changes in the Xsan/SNFS space were that Xsan 4 now supports an fsm telling all of its clients to unmount a volume. I do not know what plans, if any, they have to support this functionality. Also, I do not know what impact the new-and-not-understood messages fsm and fsmpm will send clients will have on the StornextFX clients, nor if there are any other issues of concern.
